possible fix?

For me the fix seemed to be quite simple! My screen often started to give me ghost touches after a charge or using my headphones, so I thought the problem must lie somewhere around these two connectors. When I took back cover off, I could see that the lower main board can be moved a little by the USB charge cable, as it is not glued on strong enough. So this can cause the digitizer connector to get loose! I glued the main board down with 2 sided adhesive, attached the digitizer connector properly and added little stripes of tape to the backside of the black shield to hold the digitizer connector in place in the future. For now I have not had any problems anymore, and this realy seemed to have been the issue and fix!

Hope this can help

Hello guys, my touchscreen going crazy whenever I'm charging the phone. Doesn't receive input half of the time. No matter which charger / rom / kernel I try with, problem still there. (Currently on CloudyG2 2.2)

The weird thing, i tried to downgrade to Jellybean to see if the problem is still there. Guess what? It's gone. then gone back to KitKat and boom! it's back :( even tried to open up my phone and make sure the digitizer is connected as it should be and it is...

Moreover, knock-on is gone (tried to updated touch firmware, didn't help).. Anybody knows the problems?

brb throwing my phone on the wall. anyway to update the touch firmware manually?

Thank you so much! The erratic ghost touches were driving me crazy. I tried this today, and it seems to have fixed the issue. I'm keeping my fingers crossed that it doesn't come back.
[G2 Q&A, Help & Troubleshooting] player911:
Are you updating your touchscreen drivers from the secret LG menu?

Unless you take an OTA, it doesnt get updated. Also Cloudy flashes a different touchscreen firmware that support knock code and incompatible with kitkat. Read his thread.

Best option is to flash a kdz back to 12A or something, upgrade to the latest OTA, root and TWRP. Honestly I did that after flashing different G3 roms. I noticed a big difference. Signal is better and no touchscreen issues.
[G2 Q&A, Help & Troubleshooting] The_Snake:
Hello everyone,

I have bought my LG G2 in feb/2015 but unfortunately I dropped it and the screen was damaged. So I bought a new screen/digitizer assembly and changed it.

It worked fine for two weeks or so, but then the nightmare began. While using the cellphone normally, the ghost touches started at a specific area on the screen. Then they spreaded out to another areas, but as it looks, it's just on a straight line across the screen.

The thing is that the phone works fine for a day or two, but then, when you pick it up in the morning from the charger, the ghost touches starts happening again.

Here is a screenshot of the affected area, caught using the "Yet Another Multi Touch Test" app:

(You have to copy and paste this, I'm sorry this is because this is my first post and I can't post external links).

EDIT: By the way, my phone has no dead zone when it's working normally. Although, I have an almost unresponsive touchscreen while "the ghost is playing".
[G2 Q&A, Help & Troubleshooting] caseychanfc:
Still sounds like a software issue to me, as it's so inconsistent - sometimes touch would work perfectly but other times it just spazzes out. I'm experiencing this problem on my LG optimus G running kitkat (G2 UI!) and had exactly the same problem as described! One thing I have tried on my phone that seems to work is go into accessibility and change touch recognition time to "long", seems to work fine now, hope this might help those having thr problem on the G2 as it sounds pretty darn similar

Some dead spots at the screen

I am also having the issue in LG G2(D802) of some dead spots of almost 0.3inches(horizontal) at screen which doesn't responds to touch input, and lower left side of screen is slow to respond.

What are the possible solution for it? whether I have to replace the Touch screen and digitizer, or is it some kind of loose connection problem or some software issue
[G2 Q&A, Help & Troubleshooting] stellaxtine:
I just wanted to pop in and say the folded-up-piece-of-paper method someone posted a while ago worked to fix the ghost touches.

I had pretty much given up on my G2 and have been using an older phone to ride out my contract, so I hadn't used it in several months. I got my G2 when it was first released, back in 2013, and the problems literally all popped up the day my warranty ran out. Anyway, the other day, I took apart the entire phone and tried to see if anything was loose or bent, blew on connectors in case there was any dust or debris, and then put it all back together, with the piece of paper wedged in. The whole screen worked for several days and I was hopeful, even transferred everything back onto the G2, but the top section has gone dead again. No ghost touches though, so the phone is still usable for the most part, but it is pretty annoying. I'm going to try the freezer trick, because before I did the paper trick, I noticed that I was able to use my phone for a couple days after it had been turned off for a long time before the screen began to act up again.
[G2 Q&A, Help & Troubleshooting] MAZEvGG:

Hi. I tried this today, too. Still the same ghost touches. Seems I need a new phone. :(
[G2 Q&A, Help & Troubleshooting] finger11:
Can you fix the link?

My touchscreen issues started about a month ago and it's just getting worse. A good portion of the middle lower half of the screen doesn't work at all. Tried taking it apart and seeing if the connectors were off like the one guy posted (if you have a clearer pic of what you did I'd appreciate it) but nothing helped. Now the area with the Home button doesn't work. I have an extended warranty but I can't even swipe in TWRP to put stock back on or try a different ROM... *sigh*

Hi everyone,

I have been facing the touch screen issue for a while until recently my pull down menu is not working other than 1/8 inch from the left. Screen sometimes becomes unresponsive, when scrolling things get selected. Turning the screen off and on solves few issues listed above but not the pull down menu.

My software is the original 4.2.2 that came with the device and my phone is rooted. My phone is Verizon.

Would unrooting and updating the software solve these issues? If yes, can someone give me a link for Verizon unroot and update process? There are several threads about this but not sure which is the best one.

Thank you.

Update: I unroot and updated to lollipop 5.02 directly from Verizon and still facing the same problems so it looks like it is a hardware problem and probably software as well. Turning the screen off and on fixes the most of the screen issues except the pull down menu.

Lg g2 touch issue

I am using LG G2 and the problem I am facing is

Irresponsive touch , on notification bar, middle of screen , and uper part of middle screen

My Screen is totally fine there is no crack on it the picture seems good with out any pixels broken

And sometime touch moves it self without my instructions and i was not allowed by the phone to do any thing which is most worst thing for any user

So plz suggeste me what to do

Should i change only digitizer or whole touch panel

Need help
[G2 Q&A, Help & Troubleshooting] tiguy99:
You need a new digitizer.

1. You can replace it by itself ....very hard for a beginner and next to impossible for a non technical person

2. You can replace the entire screen assembly...much easier and possible if you can follow instructions

3. You can replace the screen and frame assembly...easiest quickest path most people decide to take

The price goes from $15-75.00 cheap to expensive depending on the level of difficulty I listed above.

Hi, I was having this issue so I tried changing to a custom ROM. While doing it I did a mistake and used LG Software to recover and restore to 5.0.2 (previously i had 4.4.2). While the row is still unresponsive, now I have another problem that is touches take a long time to get recognized. I need to hold down for like 2 seconds before it registers the touch. I have enabled the developer settings to see touches on screen and it really only reads the touches after a while. How can I fix this issue? Not even talking about the bad area.

Thanks
[G2 Q&A, Help & Troubleshooting] muddy jackals:
I have exactly the same problem. It works if I'm touching the screen for 2 seconds, for now at least.

My G2 (D802 - international version) is 1 year old. 2 months ago they replaced the screen (3rd party I guess) because my screen was broken due to a fall. After replacement there has always been a small dead row at the bottom but it didn't annoy me. One week ago the screen suddenly stopped working. The only fix was to push the power button and turn on the screen again. A few days later it completely stopped working.

I decided to open up the phone and check out the digiter's connector. After removing the back cover, there were moments that the screen was fully working, no ghost touches or dead zones at all, an hour later, it didn't work anymore. Very random. After putting the back cover back the problem returned: no response at all.

After reading the fix with the tape to keep the digitizer connecter in place, I tried pushing the area where the digitizer connection is located. If I pushed hard enough, I could use the phone again, telling me the problem/fix was obvious. So I tried the tape trick, without succes.

Now the back cover is again removed and today I tried some hardware tests via the hidden menu, I did an error check of my last upgrade (lollipop) via LG pc suite, changed the knock on/off function etc. and now my screen works as described in my first sentence: 2 seconds delay touch and a dead row in the middle of the screen.

I'm still not sure if this is a software or hardware problem. The randomness tells me it's software, the fact that putting pressure on the digitizer connector area helps, tells me it's hardware.

Still hoping for a fix. In the meantime I keep searching, reading and trying.

The Deadzone

and..

The Phantom touch twitchy screens..

Done.. (at least for me) no more..

We are Bending the frame everyone, we are bending the frame..

and it's grounding out the digitizer.. some report the overheating as well when it starts twitching.. (This can lead to burning out the 3 electrical lead lines on the ribbon if continued fighting with screen without shutting screen off)

Figured it out today, have had the deadspot on a new untouched d800 3 weeks after turning the thing on.. and the twitching touches, God that's a Mess of agony..

Had a thought, used a machinist straight edge, showed the curve i felt was the cause, after reading every page of this thread, and a thought of when it started (after a scooter ride with the g2 in my back pocket)...

Ta daa i see a gap under the straight edge..

so i (as a test) held it in my left hand with fingers pulling back on the top, while my thumb pulled on the bottom, and my index finger knuckle pressing the back, causing a pressure Flex.. Low and Behold i am writing in the deadzone with the quicknote.. "?" Got to be Kidding me..

okay maybe i'm on to something..

Placed phone between 2 dvd cases face down with a paper over it to prevent scratching, and a 15 lbs weight in the center Flexing the phone..

2 hrs.. i am Currently using my thought it was dead g2 d800, to type these findings..

Got to be Kidding me..

The flex in the pocket causes frame bend and leads to the digitizer ribbon to arc out on the frame.. and LG charges 153.00 to bend it back straight.. Yes i sent mine to Texas..

Glad i said "what out of warranty? Send it back to me now" i'll figure it out..

Keep them out of your pockets people..

or at Least, flip it around to your other pocket screen out..

and swap left right, vise versa against the curve..

unbelievable..

And no one figured "Bendgate" could happen to an LG

remember the iphone troubles..

Come on LG.. own up and let the cat out of the bag..

stand up fix it, and release another small phone with a huge screen, we love em..

Everyone puts the phone in their back pocket screen to butt

and do da do.. bending the frame..

Let's flex it back the other way, and Stop giving LG in Texas our credit card numbers..
